DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 597,290, dated January 11, 1898.

Application filed August 3, 189'?- Serial No. 646,931. (No model.)

To aZZ whom it may concern:

Be it known that I, AUGUST LANGE, of Scribner, in the county of Dodge and State of Nebraska, have invented certain new and useful Improvements in Draft-Equalizers or Four-Horse Eveners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates'to draftequalizers or four-horse eveners; and it consists of the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

The object of the invention is to so arrange the several parts of the draft equalizer or evener of the character specified that the pulling tension of the animals will be equalized at all points by means which are simple and effective in their construction and operation,

strong and durable, easily and readily adjusted, and comparatively inexpensive in the cost of manufacture. a p

In the accompanying drawings, Figure 1 is a plan view of-a draft equalizer or evener embodying the invention. Fig. 2 is a cross-section on the line as of Fig. 1.

Referring to the drawings, wherein similar numerals of reference are employed to indicate corresponding parts in the views, the numeral 1 designates a main draft-bar, to which a plow-clevis or other suitable attaching device 2 is connected. ,To one end of the said draft-bar a singlet-rec 3 is movably attached, and at the opposite end of the said draft-bar a supplemental draft-beam at is movably connected bya clip 5. The point of attachment of the supplemental draft-beam 4 is considerably nearer the point of attachment of the clevis 2 than the point of attachment of the singletree 3 is to the said clevis.

The clevis 2 has a metallic strap 6 extending under the main draft-bar 1, and to the front thereoi is secured the lower end of a vertically-disposed metal bar '7, also movably attached to one end of the supplemental draftbeam 4, and to the upper angular end of the bar 7 a singletree 8 is mot-ably connected. Extending outwardly from the under side of the main draft-beam 1 is a v brace 9, having a transversely-anal]ged metallic bar 10 connected thereto, the free end of the said bar 10 being formed with a series of apertures 11. The rear ends of the said brace are secured to the main draft-bar l, and also attached to the metal bar 10 are a pair of connectingstraps l2 and 13, which at their front ends embrace opposite sides of the said metal bar 10, and at the rear the one 12 is secured to a doubletree 14, pivotally carried by the end of the supplemental draft-beam 4: opposite that to which the singletree S'is secured. The other connecting-strap 13 passes under the adjacent end of the doubletree 14c and extends a suitable distance to the rear loosely over said draft-beam and has a rear angular 1im iting-bend to engage the rear of said draftbeam to prevent thebar 10 from being drawn too far forward. The said doubletrec 14; is held in pivotal connection with the main draft-bar 1 by a clip 15, and to the end of the said doubletree opposite to that engaged by the connecting-braces l2 and 13 a singletree 16 is movably secured by means of a pair of links 17. The bar 10 is adapted to have its apertures 11 adjustably engaged by a rearwardly-extendin g hook 18, attached to a singletreel and in the attachment of the doubletree 14: its pivotal point is located at one side of its center.

From the foregoin g it will be observed that the singletrees 3 and 19 transmit the draft to opposite ends of the main draft-bar 1, the singletree 19 acting through the metal bar 10 and the V-brace 9. The supplemental draft beam 4 also transmits the draft to the inner end of the main draft-bar 1 and through the metallic strap 6 of the clevis 2 to a point near the center of said draft-bar. An equalization is set up at this point by means of the singletree S, which not only engages the one end of the supplemental draft-beam a, but also the metallic strap 6, and, further, the doubletree 14 balances the tension at the opposite side to that at which it is located by means of the singletree 16 and the singletree 18, the latter being also attached to the said I the several parts also permit adjustment of the several connected devices to favor a weak horse.

The advantages of the equalizer or evener heretofore set forth will be readily appreciated by those skilled in the art, and it is unnecessary to further elaborate upon the same.

It is obviously apparent that many minor changes in the details of construction and arrangement of the several parts might be made Without in the least departing from the nature or spirit of the invention.

Having thus described the invention, What is claimed as new is- A draft equalizer or evener comprising a main draft-bar, a singletree attached to one end of said draft-bar, a supplemental draftbeam connected to the opposite end of said draft-bar, a clevis near the point of attachment of the supplemental draft-beam having a metallic strap extending therefrom, a vertical metallic bar attached to the front end of said metallic strap and to the supplemental draft-beam, a transverse metallic bar secured to the main draft-bar and located in advance of the supplemental draft-bar, a doubletree attached to said supplementaldraft beam and to the said transverse metal bar, and singletrees movably attached to the main draft-bar, the said vertical bar, transverse bar and doubletree, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
